Chocolate and diamonds: Why volcanoes could be 'a girl's best friend'

Scientists have discovered a previously unrecognized volcanic process, similar to one that is used in chocolate manufacturing, which gives important new insights into the dynamics of volcanic eruptions. The scientists investigated how a process called ‘fluidized spray granulation’ can occur during kimberlite eruptions to produce well-rounded particles containing fragments from the Earth’s mantle, most notably diamonds.
